Supertext for Polylang

Adds Supertext as a native machine-translation service in Polylang Pro, so it appears in Languages → Settings → Machine Translation right next to DeepL. Content is translated directly through Supertext — no DeepL proxy required. It also adds human (professional) translation orders directly from WordPress, and translation files: export for translation (XLIFF 1.2 or HTML) and import of translated files (Supertext SDK 0.5.0).

How it works

Polylang Pro's MT layer is built around three swappable interfaces. This plugin implements all three:

File	Implements	Role
includes/Machine_Translation/Service.php	Service_Interface	Identity, icon, language-code mapping, wiring
includes/Machine_Translation/Client.php	Client_Interface	The actual translate() / get_usage() / key check
includes/Machine_Translation/Settings.php	Settings_Interface	The settings form (API key, endpoint, language mapping with Translation review); its key check is the Commando Center's

The service is registered through the pll_mt_services filter (see the patch below).

Translation protocol — Supertext AI file translation

The client uses Supertext's AI file translation endpoints (https://api.supertext.com/v1/, Authorization: Supertext-Auth-Key {key}), not the text endpoint. File translation accepts up to 1,000,000 characters per request, so a whole post (title + content + excerpt + metas) is sent as a single call — avoiding the text endpoint's 10k-char / 5-req-per-second limits.

Because the file endpoint is asynchronous, Client::translate() performs the full round-trip synchronously within Polylang's MT contract. The protocol is done by the official Supertext PHP SDK (Supertext/Supertext-API-SDK-and-Guide), shipped inside the plugin in includes/Sdk/ (namespace Supertext\Polylang\Sdk, so it can't clash with another plugin that ships the SDK); HTTP goes through WordPress (wp_remote_request(), Machine_Translation\Wp_Http_Transport):

1. Serialize the entity's strings into one HTML document, each wrapped in <div data-st-id="N">…</div> (Supertext translates each such element on its own and preserves markup/attributes).
2. POST /translate/ai/file (multipart) → file_id.
3. Poll GET /translate/ai/file/{file_id}/status every ~2s until done (handling translating / error / limit_exceeded / deleted).
4. GET /translate/ai/file/{file_id}/translation → translated HTML.
5. Split by data-st-id and map back onto the entries; DELETE the file.

HTTP 429 (Supertext's per-second rate limit) is retried up to 4 times (Retry-After, else 1/2/4/8 s). A pasted Supertext-Auth-Key prefix on the API key is stripped. Errors come back as WP_Error codes supertext_<code> (e.g. supertext_invalid_language_pair, supertext_quota_exceeded, supertext_unsupported_language, supertext_unsupported_feature), as before; every SDK error code has its own translated message in Client::to_wp_error().

The SDK provides the translation client and the API key check (Client::checkApiKey(), Protocol::apiKeyFingerprint(), Supertext::SDK_VERSION); version reports are Supertext Plugin Health's. Never edit includes/Sdk/: fix the SDK in its own repository, then run scripts/vendor-sdk.sh [ref] (SDK_DIR=/path/to/clone uses a local clone); includes/Sdk/COMMIT names the revision. Human (professional) translation orders use a different Supertext API and keep their own client (includes/Human_Translation/).

⚠️ This blocks the request while polling. AI file translation is usually quick, but for very large content it can approach PHP execution limits. A future iteration could move this to a background job. Polling interval/timeout are filterable (see below).

Translations is called once per entity (post, linked term), so a single post translation is a small number of file calls, comfortably under the file endpoint's 1-req-per-second cap.

Filters

Filter	Default	Purpose
supertext_polylang_endpoint	https://api.supertext.com/v1/	API base URL (also settable in the UI)
supertext_polylang_auth_headers	Authorization: Supertext-Auth-Key {key}, Accept, User-Agent	Headers of every AI request
supertext_polylang_review_endpoint	SUPERTEXT_REVIEW_URL (constant, else environment variable), else https://localizationreview-production.up.railway.app/v1/	Base URL of the review service for languages with Translation review on ('' = review off for every language), see Translation review
supertext_polylang_language_code	The mapped code, else the exact match of the locale, else the SDK default (also for the locale without _formal/_informal), else ''	The Supertext target code of a Polylang language ('' = not supported: unsupported_language); wins over the mapping drop-down, which then says so
supertext_polylang_poll_interval	2 (seconds)	Status poll interval
supertext_polylang_poll_timeout	180 (seconds)	Max time to wait for done
supertext_polylang_screenshot_endpoint	https://vibeboost.me/api/screenshot	VibeBoost Screenshots capture endpoint used to attach a page screenshot (DocumentTypeId 3) to human orders

Politeness (formal/informal) is sent only for targets where Languages::supportsPoliteness() is true: the language's Formality in the mapping (preselected from the locale), else *_formal → more, *_informal → less, else Supertext decides.

Language codes

Supertext accepts only the codes of its GET features list (the SDK's Supertext\Polylang\Sdk\V1\Languages, 28 sources and 37 targets): sources bare (en), targets regional only for de/en/fr/it/pt (de-CH, en-US, pt-BR), a script for zh/sr (zh-Hans, sr-Latn), gsw-u-sd-chzh/gsw-u-sd-chbe, and bare for all others (es, nl, sl, fi, ja). Anything else is rejected with INVALID_LANGUAGE_PAIR.

A Polylang language is resolved by its locale (Service::resolve_target(), Machine_Translation\Language_Codes, no WordPress dependency, tests/unit/cases/LanguageCodesTest.php):

1. the administrator's mapping: a drop-down per Polylang language (Language mapping in the Supertext section of Polylang's machine-translation settings, stored as machine_translation_services.supertext.languages = Polylang slug → Supertext code), then the supertext_polylang_language_code filter (wins; the mapping table says so);
2. else an exact match of the locale, apart from case and _/- (de_CH → de-CH);
3. else the SDK default (Languages::target() → defaultTarget(), SDK 0.4.0): de/en/fr/ it/pt → de-DE/en-US/fr-FR/it-IT/pt-PT, zh → zh-Hans, sr → sr-Latn, zh_TW/zh_HK/zh_MO → zh-Hant, zh_CN/zh_SG → zh-Hans, a region of a bare target → the bare target (es_ES → es, nl_NL → nl);
4. else (WordPress-specific, Language_Codes::suggest()) the same for the locale without its formal/informal variant: de_DE_formal → de-DE, de_CH_informal → de-CH, nl_NL_formal → nl;
5. else the SDK error unsupported_language: nothing is sent, and the editor gets supertext_unsupported_language naming the language and the drop-down to set.

Nothing else is guessed: en_IE, de_LI, fr_BE, gsw, sr_RS, ca_valencia, pt_PT_ao90 need a mapping. The drop-down (Language_Codes::targets(), the SDK's targetOptions() as Name (code), names localized with PHP intl's Locale::getDisplayName() in the user's back-end language where intl is installed, else English) preselects the saved code, else the suggestion of steps 2–4 (Language_Codes::suggest()), else — choose —. So the screen and the translation always agree, and an untouched mapping behaves like the suggestion. Saving is validated server-side (Service::sanitize_saved_options() on pre_update_option_polylang): only Supertext's targets are stored (in Supertext's spelling), anything else becomes ''; formality only more/less and only for a target that offers it.

Upgrading from earlier versions needs no migration: the option is the same slug → code map; a blank entry (formerly Automatic, an exact match) now shows and uses the suggestion, which for every locale that had an exact match is the same code.

One mapping serves both directions: the source is Languages::source() of the language's target code (de-CH → de), so a source language needs no separate setting. The mapping table shows each language's status, and the status panel on Supertext → Settings lists languages without a mapping and without a default.

Formality (machine_translation_services.supertext.politeness = slug → more/less/'') is offered and sent only where Languages::supportsPoliteness() is true (the drop-down shows or hides it as the language changes); it is preselected from the locale (*_formal → Formal, *_informal → Informal). Otherwise nothing is sent (Supertext would answer unsupported_feature).

Translation review

Translation review is a checkbox per Polylang language in the mapping table (stored as machine_translation_services.supertext.review = slug → bool, off by default; a hidden 0 before each box saves an untick; Service::sanitize_saved_options() keeps booleans only; no migration: a missing entry is off). Translations into a language with review on go through Supertext's review service, the translation proxy of Supertext Localization Review: Client::route_for() picks the base URL per target language and Client::sdk() builds the SDK client for it with the same key, timeouts, transport (Wp_Http_Transport) and User-Agent (supertext-wordpress-polylang/<version>, the version of the reports). The SDK's translateTexts() does upload, status, download and delete on that one client, so a job is always collected where it was submitted. The proxy speaks the same API v1, forwards to the live Supertext API with the plugin's key, stores every segment per key and serves reviewers' corrections on the next upload, so nothing else changes.

The review URL is Client::review_url(): the SUPERTEXT_REVIEW_URL constant, else the environment variable, else Client::REVIEW_URL, then the supertext_polylang_review_endpoint filter. '' (or the same URL as the API) turns review off for every language. The key check, Commando Center reports, translation files (export/import, no API calls) and human (professional) translation orders never use the review service; an authentication failure through it isn't reported to the Commando Center as a key check result. Tests: MachineTranslationClientTest (a review language's four calls go to the review URL, others directly, the key check directly, an empty URL or the API's own URL turns it off, the default is the review service, saved values are booleans).

Known limitations: corrections reach WordPress only with the next translation (no push); the review service only works with live keys.

Translation files: export for translation / import translation

Besides AI and human translation, editors can export a post or page as a file, have it translated elsewhere and import the result: the Export for translation row action in the posts and pages lists opens Supertext → Translation files, where they choose XLIFF 1.2 (for translation tools such as Trados, memoQ or Phrase; several languages in one file) or HTML (one language per file, for translators or Supertext's web app, which keeps the file's head and data-st-id attributes), and later upload the translated file. The import saves drafts through the same write-back as human orders and shows what was imported and what was skipped (source changed since the export, not translated, formatting changed, not in the file). Files over 10 MB, files from another system and translations that add markup the source doesn't have are refused; uploads aren't stored. No screenshot yet: the screenshots come from a live site with Polylang Pro.

Export for translation (XLIFF 1.2 or HTML) and Import translation with the SDK's TranslationFiles (SDK 0.5.0, Supertext\Polylang\Sdk\Files; integration guide → Translation files: XLIFF and HTML). Nothing here calls the API, and no API key is needed.

File	Role
includes/Admin/Files_Page.php	Supertext → Translation files (edit_posts): the export form (opened from the Export for translation row action in the posts/pages lists, next to the Supertext bulk actions), the download (admin-post.php?action=supertext_polylang_export_file, nonce, edit_post), the upload (…_import_file, nonce; over 10 MB refused before reading; parsed in memory, never stored) and the summary (kept 60 s in a per-user transient for the redirect). Registered only with Polylang Pro.
includes/Files/Translation_File_Glue.php	No WordPress dependency (unit-tested with a fake store, tests/unit/cases/FileExportImportTest.php): builds the jobs, checks imported jobs, counts the results, hands ok texts (and source_changed ones with the option) to the store.
includes/Files/Polylang_File_Store.php	Segments from Human_Translation\Content::collect() (Polylang's export pipeline with include_translated_items, the entries the AI client sends, all as HTML like the AI client), keyed by Polylang's translation context; permissions; write-back through Human_Translation\Writeback::save_map() (Polylang's MT Processor::save(), shared with human orders: creates or updates the linked translation as a draft, YOOtheme/ACF write-back).

• Job metadata: plugin = supertext-wordpress-polylang; reference = post:<post id>:<Polylang language slug> (e.g. post:42:de; anything else is not found); targetLanguage = Service::resolve_target() (the mapping, an exact match, the default; the supertext_polylang_language_code filter applies), sourceLanguage = the post language's code in its source form (as the AI client sends it); a language without a Supertext code is sent as its locale with - for _ (en_IE → en-IE), so it doesn't block an export. File names wordpress-<post id>-<target>.xlf / .html, wordpress-<post id>.xlf for several languages.
• Import checks per job: plugin is ours (else other system), the reference parses and the post exists with a Polylang language (not found), the language exists and isn't the post's own (no language), the user may edit_post the original and its translation, or create a post of its type (WordPress's Sorry, you are not allowed to edit this post.). untranslated, invalid_markup and missing are only counted.

Commando Center: version reports, API key check, ping

Protocol: Commando-Center-Supertext-Translation → docs/DEVELOPER.md → Report protocol. Supertext Plugin Health's InstallationReporter, reportsEnabled() and pingResponse() implement it, with the SDK's checkApiKey() and apiKeyFingerprint() as its key checker and Supertext::SDK_VERSION as sdk_version; includes/Reporting/Reporting.php (no WordPress functions) loads the state, runs one reporter action and stores the new state, never throwing; includes/Reporting/Commando.php gives it what WordPress knows and wires the hooks.

• Setting: version_reports in the option supertext_polylang_settings (Send version information to Supertext, on by default, on Supertext → Settings). SUPERTEXT_VERSION_REPORTS (0/false/off/no, 1/true/on/yes) on the server wins (reportsEnabled()); the page says so. Off: no reports, ping 404. SUPERTEXT_REPORT_URL sends reports elsewhere (tests: a fake transport).
• Report fields: site_url = home_url( '/' ); plugin supertext-wordpress-polylang with SUPERTEXT_POLYLANG_VERSION (the plugin header's version); system WordPress with get_bloginfo( 'version' ); runtime PHP; callback.url = rest_url( 'supertext/v1/ping' ). HTTP goes through Wp_Http_Transport (wp_remote_request(); Plugin Health's reports via Reporting\Report_Transport, which only converts between the two libraries' HTTP classes), with their timeouts (3 s per report, 10 s for the key check). The key check uses the Supertext environment chosen in the settings.
• When:
  • afterSettingsSaved: Polylang's machine-translation save calls Settings::is_api_key_valid(), which runs it with the key and environment being saved and returns the check's message as Polylang's notice; the update_option_polylang hook runs it on shutdown when the Supertext options changed without that call. The save of Supertext → Settings (pre_update_option_supertext_polylang_settings, options.php) runs it with the new setting and shows the message as a settings notice. At most once per request.
  • onRequest: admin_init on the Supertext pages and Polylang's settings page, and every AI translation (Client::translate_segments()). Runs once per request on shutdown, after fastcgi_finish_request() where available. Never on front-end views.
  • authenticationFailed: an AI translation failed with authentication_failure (HTTP 401/403); replaces onRequest for that request.
  • testConnection: Test connection in the status panel (admin-post action supertext_polylang_test_connection; the result is shown once on the next page view).
• State: Plugin Health's ReporterState JSON in the option supertext_polylang_reporter (not autoloaded); the same JSON the Supertext SDK 0.1–0.2 reporter stored, so sites keep their history (no new installed report). Unreadable state is treated as empty. The API key is never stored, sent or logged; only the SDK's fingerprint is kept. Errors are logged only with WP_DEBUG.
• Ping: REST route GET /wp-json/supertext/v1/ping (permission_callback __return_true, no login or nonce) answers pingResponse()'s status, headers (Cache-Control: no-store) and body.
• Messages: Commando::message() has the center's five texts, with the account and API key links (new tab) for invalid and missing (bare URLs where Polylang shows plain text).
• Tests: tests/unit/cases/ReportingTest.php and CommandoTest.php use a fake transport and SUPERTEXT_REPORT_URL pointing at 127.0.0.1, so they never reach the live center.

Supertext Plugin Health

Supertext Plugin Health (in the Commando Center's repository, plugin-health/) is the dependency-free library every Supertext plugin uses for the version reports, the report of the API key check's result and the answer of the ping endpoint; the key check itself is the SDK's. The plugin ships its PHP part in includes/PluginHealth/ (namespace Supertext\Polylang\PluginHealth instead of Supertext\PluginHealth, loaded by the plugin's own autoloader and checked by PHPStan like includes/Sdk/); COMMIT and VERSION there name the revision. Never edit includes/PluginHealth/: fix it in Commando-Center-Supertext-Translation/plugin-health, then run scripts/vendor-plugin-health.sh <tag> (e.g. plugin-health-v0.1.0; default main; PLUGIN_HEALTH_DIR=/path/to/clone uses a local clone as it is).

Interface languages

The plugin's strings use the text domain supertext-polylang. German, French and Italian are in languages/supertext-polylang-{de_DE,fr_FR,it_IT}.po (formal address: Sie, vous, Lei); the plugin loads the matching .mo on init for each user's back-end language, with regional locales falling back to their language (de_CH, de_DE_formal → de_DE). After changing a .po, run php scripts/compile-translations.php (no gettext tools needed); tests/unit/cases/TranslationFilesTest.php checks that the three files have the same strings, placeholders and URLs, that the .mo files are current, and that every string of the Supertext machine-translation settings, the AI error messages and the Commando Center is translated. New or changed strings get all three translations in the same commit. Older screens (orders, human translation, integrations) are still English only.

YOOtheme Pro page-builder integration

YOOtheme stores each page's layout as JSON inside an HTML comment in post_content (<!-- {…} -->). Translating that blob with any translator corrupts the JSON, so this plugin translates it field-by-field via Polylang's export/import hooks (pll_export_post_fields, pll_after_post_export, pll_filter_translated_post) — the same pipeline used by both XLIFF and the Supertext MT path. Only string-valued props in the translatable set are touched; structure, CSS, ids, and URLs are left intact. See includes/Integrations/YooTheme/. The hooks register automatically — no configuration needed.

YOOtheme filters

Filter	Default	Purpose
supertext_polylang_yootheme_fields	['content','title','meta','alt','image_alt']	Prop keys whose string values are translated
supertext_polylang_yootheme_skip_content_types	['code']	Element types whose content prop must NOT be translated (raw code)

// Translate an extra YOOtheme text prop (e.g. a custom element's "subtitle").
add_filter( 'supertext_polylang_yootheme_fields', function ( array $keys ): array {
    $keys[] = 'subtitle';
    return $keys;
} );

All filters above are applied on every run with their built-in defaults, so the plugin works out of the box. Adding a callback (in an mu-plugin, theme functions.php, or this plugin) is only needed to extend the defaults.

Gravity Forms integration

Gravity Forms aren't posts — they live in Gravity Forms' own tables — so they can't ride Polylang's post pipeline like YOOtheme does. Instead the integration (includes/Integrations/GravityForms/) collects a form's visible strings, registers them with Polylang, and swaps them at render time.

• Collection — Fields::collect() walks a form and returns its translatable strings keyed by a stable path (title, button.text, field.7.label, field.7.choice.2.text, field.9.input.1.customLabel), keyed by field id so the paths survive field reordering. Covered properties: the form title/description/button text, and per field its label, description, placeholder, errorMessage and content, each choice's text, and each input's placeholder and sub-label.
• Sub-labels — multi-input fields (Name, Email-with-confirmation, …) render an input's customLabel when the admin set one, and only fall back to the built-in label otherwise. Collection and render therefore target customLabel when present (that is what the visitor actually sees); inputs flagged isHidden (e.g. an unused name prefix/suffix) are skipped. See Fields::sublabel_prop(). Getting this wrong stores a translation that never displays — see tests/unit/cases/GravityFormsFieldsTest.php.
• Storage — strings are registered with Polylang (pll_register_string, grouped per form) and their translations live in Polylang's own per-language store (PLL_MO), keyed by the source string value. A Supertext AI translation, an edit in Polylang's grid and an edit here are all the same record. Registration is per-request and gated by a persistent opt-in flag (Strings::is_enabled() — the Add to String Translations button); front-end rendering does not depend on that flag.
• Render — Integration::translate_form() hooks gform_pre_render and gform_pre_validation, and on a non-default language rewrites each visible string through Fields::apply_callback() with pll__(). Untranslated strings fall back to the source.

Required Polylang patch (one line)

Polylang Pro keeps its MT services in a hardcoded const with no registration hook:

// src/modules/Machine_Translation/Factory.php
const SERVICES = array( Deepl::class );

To let plugins register a service, Factory::get_classnames() must expose a filter. This single method feeds three consumers — the service picker, the option defaults, and the strict option storage schema (additionalProperties: false, so without it our supertext options are stripped on save). Change:

public static function get_classnames(): array {
    return self::SERVICES;
}

to:

public static function get_classnames(): array {
    /**
     * Filters the list of machine translation service class names.
     *
     * @param string[] $services List of service class names.
     */
    return apply_filters( 'pll_mt_services', self::SERVICES );
}

Without this patch the plugin loads but stays inert, and shows an admin notice saying so.

⚠️ This patches Polylang Pro's own code, so it must be re-applied after every Polylang update. It is a minimal, upstreamable change — ideally Polylang/WP Syntex adds the filter to core so no patch is needed.

Activating Supertext

1. Apply the patch above and activate this plugin.
2. Languages → Settings → Machine Translation → enable machine translation.
3. Choose Supertext, enter the API key (no Supertext account yet? create one at supertext.com; then generate the key at Supertext → Integrations → API, requires the Admin role), and map each Polylang language to its Supertext code (the fields are pre-filled with BCP-47 suggestions; adjust where Supertext differs). Save.
4. is_active() becomes true once a key is stored; Supertext is then used for AI translation of posts/strings.

Note: Factory::get_active_service() returns the first configured service. If a DeepL key is also set, DeepL (listed first) wins. Leave the DeepL key empty to use Supertext.

Deployment

deploy.ps1 commits/pushes and SFTP-syncs the repo root to the demo server's .../plugins/supertext-polylang folder. README.md, .git, and the deploy scripts are excluded from the sync. The Polylang patch must be applied on the server too.

Code quality and security checks

• Checks (.github/workflows/checks.yml): on every push and pull request, actionlint and zizmor lint the workflows. On pull requests, dependency review fails a PR that adds a package with a known vulnerability (moderate or worse). Third-party actions are pinned to commit SHAs (Dependabot keeps them current); checkouts don't keep credentials (persist-credentials: false), and workflows get contents: read unless a job needs more (the release job: contents: write; the unit-test job: checks: write for its test report).
• Links (.github/workflows/links.yml): lychee checks the links in all Markdown files weekly and whenever docs change on main. Broken links open or update the issue "Broken links in the docs" (a docs push that breaks links also fails). Links that can't work from CI go in .lycheeignore (one regex per line).
• PHPStan (job phpstan in unit-tests.yml, config phpstan.neon): level 5 on the plugin's own code (supertext-polylang.php, includes/), not the tests. PHPStan and the stubs it needs (WordPress via szepeviktor/phpstan-wordpress, Polylang via wpsyntex/polylang-stubs, Gravity Forms via php-stubs/gravity-forms-stubs) are dev dependencies in tests/unit/composer.json. Polylang Pro and YOOtheme have no public stubs, so the findings about their classes (WP_Syntex\Polylang_Pro\…, PLL_Base::$curlang) are in the baseline. Locally: cd tests/unit && composer install && composer phpstan (or tests/unit/vendor/bin/phpstan analyse from the repository root). Existing findings that aren't simple to fix are listed in phpstan-baseline.neon (regenerate with tests/unit/vendor/bin/phpstan analyse --generate-baseline after fixing one). New code must not add findings.
• GitHub settings (set by Remy's setup script, not in the repo): secret scanning with push protection (a push containing a known token format is rejected; findings under Security → Secret scanning) and CodeQL default setup (findings under Security → Code scanning and as PR comments). CodeQL doesn't cover PHP, which is why this repo runs PHPStan.

Before starting work in this repo, look at its open findings: code scanning alerts, secret scanning alerts, Dependabot PRs and the "Broken links in the docs" issue.
